lClaini. (01." 126-33) 'I'his invention relates to a; multiple cooker I4in the base 1. `UpperN and lower 'doorxopenfor use asequipment inconnection withiunch stands, lunch rooms, dining rooms, restaurants,

dining'cars, as wellas in any other connection for which it may be foundapplicable.

The principal object of the invention is to pro- Vide an eiiicientmultiple unit cooker having one of the units constituting a heatingsource and with said units so constructed and arranged as to becomparatively inexpensive to operate and adapted to be readily regulatedto vary the heating capacity of the units in accordance with diierentcooking requirements.

The invention further aims to provide, in a.

manner as hereinafter set forth, a multiple unit cooker which iscomparatively simple in its construction and arrangement, strong,durable, compact, pleasing in appearance, comparatively inexpensive tomanufacture, and readily assembled.

To the above ends, and to others which may hereinafter appear, theinvention consists of such parts, and such combination of parts as fallwithin the scope of the invention as claimed.

In the drawings:-

Figure 1 is a detail sectional view of one of the cooker unitsillustrating a re box forming part of such unit, Y

Figure 2 is a section on line 2-2, Figure 1,

Figure 3 is a section illustrating the manner in which the cooking unitconstituting the hot plate is heated.

The multiple cooker includes a cooker unit 4 in the form of a stove anda hot plate unit 3 extending from one side thereof.

The unit 4 comprises a metallic base frame 1 inset as at 8 to provide ashoulder I0 around the base and formed with an inwardly extending flange9. A plate I2 forming the bottom of an ash pit is supported by arms onsaid flange. An open bottom metallic housing I6 is suitably secured tothe base 1 and on the shoulder |0. The housing I6 comprises a top wallI1, a rear wall I8, side walls I9 and 20, respectively, and

a front wall 2|. Opposed to walls I8, I9, 20,

and 2| and spaced therefrom are Vertical partition members 22, 23, 24,and 25, respectively, of heat insulating material, the members 22, 23,and 24 extending to a point adjacent the top I1 and the member 25 beingof less height. A horizontal partition member 34 connects the members22, 23 and 24 at their top. The partition members 22, 23, 24, 25, and34, together with the walls I1, I8, I9, and 2|), form air chambers 26 towhich air is admitted through openings ings 3| and '32,are formed inthewall registeringv with similar related'openings 21 and.` 28` in thepartitions-25; .Door fram'es' 29-1'andi3llf extend between relatedopenings 21 and 3| and 28 and 5 32 and are closed by upper and lowerdoors 33 and 33 respectively.

Spaced from the partitions 2|, 22, 23, 24 is an open top re box 4|formed by short metallic side and rear partitions 36 and 31 secured to10 angle irons I5 on ange I3, said partition being lined with re brick40 resting upon a grate 39. The plate-like frame 38 closes the spacebetween said partition 36 and 31 and 2|, 22, 23, and 24 at the top ofthe iire box 4|. A pair of 15 water back structures comprising, on theone hand, elements 42, 44, 45, and on the other, elements 43, 46, 41,are shown in the drawings, also a water coil structure including parts41, 48, 49, 50, 5|, 51, 58, 60, and 6|, but these struc- 20 tures needmerely be identiiied in passing since they form, per se, no part of thepresent invention.

Above the fire box 4I is an oven 63 in the form of an open front casingelement 64 suitably con- 25 nected to housing wall 2|, to seat uponpartition member 25. The front of the oven may be closed by a suitabledoor not shown. The oven 63 is spaced from the members 22, 23, 24, and34 to provide for circulation of heat around said oven 30 and is alsospaced from the iire box structure to provide a heating chamber 62between said oven and structure communicating with the space between theoven and said members. A flue 63 extending from the space surroundingsaid oven 63 provides an outlet for chamber 62. Interposed in thechamber 62, between the frame 38 and oven 63, and over the re box 4|, isa curved deflector 65 for directing heat from said chamber 62 into theunit 3. The deector 65 is shorter than the 40 chamber 22 to provide forthe passage of heat around the same to said oven. The deflector 65 isprovided intermediate its ends with an opening 66 adapted to be closedby a damper 61 suitably mounted for operation exteriorly of the 45 unit4 as by lever 65 shown in dotted lines in `Figure 3. The deflector65coacts with a flue 68,

a deflecting plate 69 and an opening 16 in housing wall I9 to directheat from the fire box 4I and chamber 62 into unit 3. The flue 68 is 50mounted in member 23 in the opening 16 and the deiiector 65 extends froma point contiguous the top of said flue to direct heat into the latter.The unit 3 comprises an open top and open rear Casing 13 of heatinsulating material form- 55 ing a heating chamber 13' into which theflue 68 opens. A baie plate 14 is provided in said casing for directingthe heat and products of combustion received from unit 4 to an outlet 15in said casing opening into an upstanding stack 16 which communicateswith the flue 63. A metallic housing 11 encloses the casing 13 in spacedrelation thereto and is mounted on suitable supports 80. A metallic hotplate proper 18 covering the casings 13 and housing 11, is disposedthereover, said plate having an overhanging curved flange 19 for apurpose which Will be apparent. Preferably the casing 13, housing'll andhot plate 18 are anchored to the housing Wall 2|.

When it is desired to utilize the maximum heating capacity of the unit3, the damper 61 is closed whereby the major part of the heat from there box 4| will be directed into said hot plate unit as will be clear. Bymanipulating the damper 61 to different positions the amount of heatpassing to said unit 3 may be decreased and heat by-passed from beneaththe deflector 65 to said oven whereby the amount of heat passing to saidunit 3 and the oven 63 may be varied in accordance with differentcooking requirements.

What I claim is:

A cooking unit comprising an open top re box, an oven above said re boxand spaced therefrom to provide a heating chamber between said box andoven, a second cooking unit extending from one side of the rst mentionedunit, said second unitl including a hot plate and having a heatingchamber under said plate provided with an inlet flue opening into thefirst mentioned heating chamber, a deflector plate extending from apoint contiguous the top of said iiue into the first mentioned heatingchamber for directing heat from the latter into said flue, saiddeflector plate being shorter than said rst men tioned chamber toprovide for the passage of heat around the same to said oven, and adamper in said deector plate for by-passing heat from beneath the latterto said oven and thereby varying the degree of heat passing to said hotplate and oven respectively.
